Miniaturized ice water cooling circulatory system

ABSTRACT

A miniaturized ice water cooling circulatory system includes an ice water tank having a drowned water pump disposed therein for pumping and conveying refrigerant into the ice water tank to convert the water in the ice water tank into ice water to be conveyed out for cooling off the heating elements in a computer mainframe. After the heating elements are cooled off, the ice water is converted into cold water to be conveyed back into the ice water tank, thus attaining effect of cooling circulation. The drowned water pump is positioned in the ice water tank so the volume of the cooling circulatory system can be diminished for facilitating the cooling circulatory system to be assembled in a computer mainframe for carrying out heat dissipation for the heating elements, having excellent effect in heat dissipation.

BACKGROUND OF THE INVENTION

A water pump 7 is connected with the water tank 2 for pumping and conveying the ice water formed by the refrigerant input tube 3 into the ice-water output tube 5 to be conveyed to the interior of the computer mainframe for lowering the temperature of the heating elements on the motherboard, and then the ice water is conveyed back into the water tank 2 through the cold-water input tube 6.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

A first preferred embodiment of a miniaturized ice water cooling circulatory system able to be installed in a computer mainframe in the present invention, as shown in FIG. 2, mainly includes an ice water tank 10, a heat collector 20, a compressor 30, a condenser 40, a dry filter 50 and a refrigerant controller 60 combined together.

The ice water tank 10 is provided with normal temperature water and a drowned water pump 11 in the interior and has its front side bored with a water intake 111 and a water outlet 112 positioned above and communicating with the water intake 111. The drowned water pump 11 has its outer circumference disposed with a refrigerant conveying tube 13 formed into several loops surrounding the outer circumference of the drowned water pump 11. The ice water tank 10 has one end provided with a refrigerant input terminal 12 and a refrigerant output terminal 13, and the refrigerant conveying tube 113 has one end inserted in the refrigerant input terminal 12 and the other end inserted in the refrigerant output terminal 13. Further, the ice water tank 10 has its upper end connected with an external ice-water output tube 14 and a cold-water input tube 15, and the ice-water output tube 14 is extended into the ice water tank 10 to connect with the water outlet 112 and has its outer end connected with the outer end of the cold-water input tube 15.

The heat-collector 20 is a metallic board with a proper thickness to be combined with the heating members inside a computer mainframe, which need dissipating heat and lowering temperature. The heat collector 20 is formed with an input terminal 21 connected with one end of the ice-water output tube 14, and an output terminal 22 connected with one end of the cold-water input tube 15, letting the ice-water output tube 14 and the cold-water input tube 15 connected in the heat collector 20. Cold water produced after the heating elements suck heat will be conveyed back to the interior of the ice water tank 10 through the cold-water input tube 15.

The compressor 30 positioned adjacent to the ice water tank 10 has one end connected with the refrigerant conveying tube 113 and another end connected with one end of a refrigerant input tube 16 as well as with the refrigerant output terminal 13 of the ice water tank 10. After sucking heat, refrigerant will be compressed by the compress or 30 and then conveyed to the refrigerant input tube 16.

The condenser 40 is connected with the refrigerant input tube 16 between the compressor 30 and the ice water tank 10 for condensing the refrigerant gas coming from the compressor 30, having a fan 41 assembled at one side for exhausting heat.

The dry filter 50 is assembled on the refrigerant input tube 16 and positioned adjacent to one end of the condenser 40.

The refrigerant controller 60 is disposed on the refrigerant input tube 16 between the ice water tank 10 and the dry filter 50 for lowering the pressure of the refrigerant gas input from the condenser 40 to enable the refrigerant to suck heat in the ice water tank 10 and carry out circulation anew.

FIG. 3 shows that the cooling circulatory system is installed in a computer mainframe 80. The cooling circulatory system is assembled in a box 70 and secured at the inner left side of the computer mainframe 80. The box 70 has its topside bored with two insert holes 71 respectively for the ice-water output tube 14 and the cold-water input tube 15 to be inserted therethrough and extended out of the box 70. The ice-water output tube 14 is connected to the water outlet 112 of the drowned water pump 11, while the cold-water input tube 15 has one end connected with the topside of the ice water tank 10. The ice-water output tube 14 and the cold-water input tube 15 respectively have the other end connected in the heat collector 20 that is combined with the heating elements 82 on the motherboard 81 in the computer mainframe 80. The compressor 30 is connected with the ice water tank 10 by the refrigerant input tube 16, while the condenser 40 is connected with both the compressor 30 and the ice water tank 10 by the refrigerant input tube 16 for carrying out circulation and conveyance of the refrigerant. In addition, the condenser 40 has its left side provided with a fan 41, and the box 70 has its right side disposed with a ventilating net 72 positioned adjacent to the condenser 40 for exhausting out heat sucked by the cooling circulatory system.

In suing the cooling circulatory system, the drowned water pump 11 is first started to let the refrigerant input tube 16 convey low-pressure liquid refrigerant gas into the refrigerant conveying tube 113 in the ice water tank 10 to have the normal-temperature water in the ice water tank 10 converted into low-temperature ice water. Then, the ice water in the ice water tank 10 is conveyed to the heat controller 20 through the ice-water output tube 14 to let the heat controller 20 cool off and suck the heat produced by the heating elements 82. Meanwhile, the ice water in the ice-water output tube 14 will heat up and become cold water to let the refrigerant gas suck heat and vaporize, and then the cold water is conveyed back to the interior of the ice water tank 10 through the cold-water input tube 15, thus achieving the objective of lowering temperature for the heat elements 82 on the motherboard 81 of a computer.

After vaporized, the refrigerant gas is conveyed to the compressor 30 through the refrigerant input tube 16 to be compressed into high-temperature gaseous refrigerant to be conveyed to the condenser 40 to be condensed into high-pressure and normal-temperature liquid refrigerant by the condenser 40. At this time, the heat in the box 70 or in the motherboard 81, sucked by the cooling circulatory system, will be exhausted out through the ventilating net 72 by the fan 41, and the high-pressure and normal-temperature liquid refrigerant coming from the condenser 40 will be conveyed to the dry filter 50 to be dried out and then conveyed to the refrigerant controller 60 for lowering temperature to let the refrigerant gas converted into low-pressure liquid refrigerant that the ice water tank 10 needs. Lastly, the low-pressure liquid refrigerant is conveyed into the ice water tank 10 for carrying out another round of cooling circulation.

A second preferred embodiment of a miniaturized ice water cooling circulatory system in the present invention, as shown in FIG. 4, has almost the same structure and function as those described in the first preferred embodiment, except that the drowned water pump 11 has its outer circumference disposed with two refrigerant conveying tubes 114, 115 formed into several loops surrounding the outer circumference of the drowned water pump 11. The two refrigerant conveying tubes 114, 115 respectively have one end connected with the refrigerant input terminal 12 and the other end connected with both the refrigerant output terminal 13 and a confluence box 90 that is connected with the refrigerant input tube 16 for increasing cooling effect.

The drowned water pump of this invention is installed in the interior of the ice water tank so the volume of the cooling circulatory system can be diminished for facilitating the cooling circulatory system to be optionally assembled inside or outside a computer mainframe, convenient in assembling and taking less space.
